This is with a 2002-01-24 build, but has been happening for a few weeks at least. It happens quite easily on Solaris, but I've also seen it on Linux. To reproduce it, go to the URL above, position the scroll bar so that the last line of text visible is partly cut off. Then scroll down. You'll see that each line that gets scrolled into view has a horizontal line of pixels missing, corresponding to where the bottom of the visible page was. Anything that forces a redraw (highlighting the text, covering and uncovering the window) restores it. This doesn't happen on all web pages, but I've managed to distill a test page which illustrates the problem. Though even this sample isn't representative of all the examples I've seen in the wild.
Attached file Test page which has the problem (deleted) —
This page shows the problem. The key here seems to be that there is an <h1> heading, preceded by normal text. This text can also be as simple as a <p> tag. If that text is removed or if the <h1> tag is changed to <h2>, the problem disappears.
Attached image An image illustrating the problem (deleted) —
Here's a picture of the problem. The font is 14pt adobe-times-iso8859-1, from Solaris 8.
This same behavior can be repeated in 4.x, if you scroll to mid-line via the slider and then select to scroll via the scrollbar arrow, you end up on mid-lines. This is easily adjusted by setting the scroll line from the slider and then scrolling via the arrow.

I do not see it in 4.77 (at least, not when looking at the same pages where it shows up in Mozilla). And it's only shown up for me in the past month in Mozilla. I honestly think that the Severity is worse than minor because it's making a good portion of the web pages I read difficult to read. If it showed up only occasionally, I wouldn't be bothered quite so much, but it's really a PITA to read some stuff now, and it hasn't always been this way.
Here's another URL which demonstrates the problem all by itself; you don't even have to scroll! I guess it's the scrolling induced by the graphics getting loaded. This'll be my last example; there's plenty of material here if someone who wants to fix the bug needs to reproduce it. http://www.citi.umich.edu/projects/smartcard/smartcard_seminar/8.html
